1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

Replication of HIV requires the Tat protein, which activates elongation of RNA polymerase II transcription at the HIV-1 promoter by interacting with the cyclin T1 (CycT1) subunit of the positive transcription elongation factor complex b (P-TEFb). The transactivation domain of Tat binds directly to the CycT1 subunit of P-TEFb and induces loop sequence-specific binding of P-TEFb onto nascent HIV-1 trans-activation responsive region (TAR) RNA. We used systematic RNA-protein photocross-linking, Western blot analysis, and protein footprinting to show that residues 252-260 of CycT1 interact with one side of the TAR RNA loop and enhance interaction of Tat residue K50 to the other side of the loop. Our results show that TAR RNA provides a scaffold for two protein partners to bind and assemble a regulatory switch in HIV replication. RNA-mediated assembly of RNA-protein complexes could be a general mechanism for stable ribonucleoprotein complex formation and a key step in regulating other cellular processes and viral replication.
